WATER- SPEGIFIGATION forming part, of Letters Patent No. 243,087, datedJune 21, 1881.

Application filed September 29, 1880.

To all whom it may concern Be it known that I, JOHN H. SWARTZ, ofBrooklyn, in the county of Kings and State of New York, have invented anImproved Water- 5 Meter, of which the following is a specification.

Figure 1 is a horizontal section of my improved watcr-meter, taken onthe plane of the line c, Fig. 2. Fig. 2 is a side view, partly insection, of the same, the line 0 k, Fig. 1, in-

IQ dicating the plane of section. Fig. 3 is a vertical cross-sectionthereof on the line 70 k, Fig. 1. Fig. 4 is a horizontal section on theline q (1, Fig. 2. Fig. 5 is a vertical section on the line k g, Fig. 4.5

class which measure a stream of water by the effect which a certainportion of the stream that passes through the meter-box has upon theregistering mechanism.

Heretofore meters of this class were regulated, principally, by a valveat the inlet-opem, ing-that is to say, at the opening at which the waterflows into the meter; but I found by many experiments that satisfactoryresults are 2 5 not obtainable whereverthere is a valve at theinlet-opening, because greater or less obstruction is necessarilyplacedinto the path ofthe water as it flows into the meter, andtherefore friction created, which will interfere with the prop- 0 ermeasuring of whatever portion of the stream is allowed to enter themeter.

My invention consists, principally, in constructing a meter -into whichthe water flows without any attempt at obstruction or regula- 3 5 tionwhatsoever, but the outlet of which is supplied with a valve forproducing the requisite degree of adjustment and regulation 5 this incontradistinction to the usual obstruction or valve at the inlet.

The invention also consists in other details of improvement, which arehereinafter more fully described. 7

1n the drawings, theletter A represents the inlet-pipe, the letter B themeter-chamber, and 5 the letterO the outlet-pipe, of the meter. The

inlet-pipe connects in suitable manner with the supply-pipe, andcontains a partition, a, which forms a 'narrow channel, I), throughwhich part of the stream passes from the inlet-pipe into 50 themeter-chamber B tangentially to the same,

This invention relates to water-meters of that (No model.)

so that the water that enters said meter-chamber B will revolve thevanes D of the recording mechanism. The main body of the stream,however, from the inlet-pipe A, lifts a valve,

E, (see Fig. 2,) and passes through a side channel, F, directly into theoutlet-pipe O.

The valve E has a downwardly-extending stem, 0, which is, below the'pipeA,connected with a suitable spring or series of springs, G, as clearlyshown in Fig. 2. The tension of this spring or set of springs G isregulated to maintain the desired proportion of stream passing by themeter by means of a sliding block,f, which is moved by a suitable screw,g, or in any other suitable manner, so that by sliding said block f andadjusting the power of the spring or springs, the meter will be adjustedto require more or less water-power to lift the valve E. Suitable cars,it, projecting from the valve straddle pins 6, as shown in Fig. 2,and 7oprevent the valve E from turning, and from being lifted too high. Thusit will be seen that the passage from the pipe A to the meterchamber Bis always unobstructed and always the same in size, permitting so muchof the 5 stream to enter the meter-bod y unobstructedly asis notpermitted to pass through the chamber F. A suitable proportion is thusallowed to enter a branch pipe, F,without affecting the meter. By meansof the adj ustiug mechanism described the valve E can be more or lessloaded either from above or'below, to regulate the degree of forcenecessary to lift it,'and consequently the proportion of the streamadmitted into the branch pipe F. The water having 8 passed through thechannel 1) into the lower part of the metenchamber B, where the vanes Dare located, (see Fig.5,) passes next through a hole, j, in a partition,I, which is placed above the lower part of the meter-chamber into theupper part, m, of said meter-chamber, and thence through a lateral hole,a, into the pipe 0, as clearly shown in Fig.5.

The size of the opening a, through which the water is discharged fromthe'meter-body, is 5 regulated by suitable slidin gpiece,p, and screw 1,or other equivalent mechanism, so that the discharge of the waterfromthe meter is more or less obstructed, according to the amount ofwater and degree of pressure or head that is conducted toward the meter.Thus, if a small stream of Water with a reduced head enters theinlet-pipe A, the valve or slide 19 may be lowered to reduce theoutlet-opening, whereas for a greater head of water and larger mainstream said valve may be raised to increase the outlet-openin g.

Normally, the outlet-opening it should be larger in cross-section orarea than the channel I). By my arrangement of adjusting the inlet tothe side channel and the outlet of the meas uring part of the stream therequisite proportion between the two streams can at all times beinsured.

I claim- 1. In a water-meter, the combination of interior partition, Z,having center vent, j, with the shell or case B, having unobstructedinletchannel I), to allow free ingress of Water into the measuring partof the meter, and with the regulating-valvep at the outlet-opening n,substantially as described.

2. The shell B of a Water-meter, provided with the unobstructedinlet-passage b and larger outlet-opening n, in combination with thevalve E and side branch, F, and with the valve 12, substantially asdescribed.

3. A Water-1n eter having inlet-channel b, and

side passage, F, and outlet 0, in combination I with the valve E andvalve 19, both said valves regulating the amount of Water going into theoutlet-pipe, substantially as described.

4. The valve E, pipe A, branch pipe F, unobstructed branch pipe b, andpartition I, in combination With the spring G, and with mechanism forregulating the Weight or pressure of the valve, substantially asdescribed.
